A history of the key code for the last pressed front-panel key is maintained by the instrument. When the
instrument is turned on, or when it is transitioning from local to remote operation, the key code is set to 0
(
display.KEY_NONE
).
Pressing the EXIT (LOCAL) key normally aborts a script. To use this function with the EXIT (LOCAL) key, you
must set
display.locallockout
to
display.LOCK
.

When using this function, use built-in constants, such as

, rather than the
numeric value, such as
103
. This allows for better forward compatibility with firmware revisions.
The OUTPUT ON/OFF control cannot be tracked by this function.
